    • A device including propulsion means extending below the water line comprising a pair of flexible fins each adapted to oscillate through an arcuate path in a generally transverse direction with respect to the central longitudinal dimension of said watercraft, and means operatively associated with said propulsion means for applying input force to said propulsion means whereby as input force is applied said flexible fins can twist to form an angle of attack for providing forward thrust with respect to the longitudinal dimension of the watercraft while moving in both directions along said arcuate path, each said fin being carried at its upper trailing edge by a fixed pivot and at its upper leading edge by a retainer which is normally engaged while being disengageable when said leading edge strikes a resistance element allowing said fin to pivot aft to clear the resistance element and re-engageable as the fin rotates forward and resumes producing thrust.
    • 一种装置,包括在水线下方延伸的推进装置,该装置包括一对柔性鳍片,每个柔性鳍片适于相对于所述水运工具的中央纵向尺寸沿大体横向方向通过弧形路径振荡,以及与所述推进装置可操作地相关联的装置, 输入力施加到所述推进装置,由此当施加输入力时,所述柔性翅片可以扭转以形成迎角,以在沿着所述弓形路径在两个方向上移动时提供相对于所述水运工具的纵向尺寸的向前推力,每个所述翅片 在其上部后缘处由固定枢轴支撑,并且在其上部前缘处由保持器承载,该保持器在所述前缘撞击阻力元件时通常接合,同时允许所述翅片向后枢转以清除阻力元件并且可重新接合为 翅片向前旋转并恢复产生推力。
